“Having six, it feels like you’re trying to control a basketball team,” the part-time DJ and producer admitted. “But it’s worth it. All my kids are great; they get along. By the time you have six, you are so well-seasoned. I can probably change a diaper with one hand and feed a kid at the same time.”

Federline — who was married to Spears, 35, for two years until they split in 2006 and went through a bitter custody battle with his ex — now amicably shares custody of his sons with her. “It wasn’t always easy, but it’s a lot easier now,” he admits.

But sharing custody with a pop star who’s in the midst of a tour means that he didn’t get to spend Father’s Day with all his children.

“I’m used to not having all my kids, and this is gonna be one of those years,” he said. “When you are coparenting, you have to be willing to give up some of the things you would really like to do. My boys will be gone, their mom’s off in Asia on tour … They are gone for the rest of the month.”

Federline, whose 2006 album, Playing With Fire, didn’t exactly generate much heat, revealed that Preston and Jayden are into music.

“Preston kind of knows how to DJ,” he told BravoTV. “He wants to learn more. I got him Ableton [music production app] on his laptop, so he kind of messes with that. He hasn’t completely dived into it, and I don’t want to force him. I want to make sure it’s something he really wants to do. He’s really big into the EDM trap music scene. He’ll come to me, ‘Have you heard this?’ Looking for music for me to play.” the EDM trap music scene. He’ll come to me, ‘Have you heard this?’ Looking for music for me to play.”
